FREDERICK JuLrUs KALDENBERG, or TARRY'rowN, NEW YORK, AssIGNoR TO M..KALDENBERG, OF SAME PLACE.

TBAcco-PIPE.

SPEGIFIGATION forming part of Letters Patent No. 552,711, dated January7, 1896.. 4

Application nea March 6,1893.l serata. 464,856. (No model.) i l certainnew and useful Improvements in Tobacco-Pipes, of which the following isa speciication.

My invention relates to pipes for smokers use, and the object of theinven tion is, in part,

air in regulated quantities to the smoke-passage inthe stem so asto'cool the smoke, and in part to provide aconvenient-constructionwhereby the nicotine distilled from the burning tobacco may be collected'and-prevented from getting into 'the smoke-passage in the stem.

lThe invention will be fully described hereinafter, and its novelfeatures carefully defined in the claims. Y

In the accompanying drawings, which serve to illustrate my invention,Figure lis a longitudinal section of a briarwood pipe embodying myimprovements= and Fig. 1a is a transverse section through the stemthereof on the line l 1 in Fig. 1. Fig. 1b is a detached perspectiveview of the metallic screw which connects the sections of the bowl. Fig.2 represents the mouthpiece and coredetached, and

, Fig. 2a is an end view of the core. Fig. 3 illustrates a slightlydierent construction of the core, the view being -a longitudinal sectionof the stem, core, mouthpiece, and a part of the bowl.

Referring primarily to the principal figures, and particularly Figs. land 2, A represents, as a whole, the bowl of a pipe, which will. be,

by preference, of briarwood, or some woodl with a figured grain, and Bthe stem of the s pipe formed integrally with the bowl. .l The bowl Ais' cut across transversely at this cut forming an upper section a,forming a receptacle for ,the tobacco, and a lower section ax,

forming a receptacle for the nicotine. -The stem B is connected withthislower section ax. In the upper part ay is the cavity af to receive thetobacco or other substance or mixture to be smoked, and the bottom ofthis cavity is' Y the smoke topassdown into a cavity a3 inthe lower partax of the bowl on its 'way to the smoke-passage in the stem.

It is desirable in wooden pipe-bowls, having a figured grain,.that theupper and lower parts of the bowl shall appear by the close--V ness ofthe joint and the continuity of the g'ured grain to be integral, and'inorder to carry out this feature I first shape the bowl and stemof thepipe in the usual way and excavate the bowl to form the cavity c. `Ithen cut the bowl transversely along the line a: as

smoothly as possible, and afterward form the cavity a". sections of thebowl together, a screw (see at y.;in,Fig.3),is formed inthe wall of thecavity a, and a screw-threaded metal ring or tubesection a4(seendetached in Fig. 1b) is set To secure the upper and lower y'tightly in the base of the upper section of the bowl in position toscrew down into 4the cavity in the lower section of the same, as seen inFig. 1. If necessary, the outer surface of the bowl may be dressed andfinished after the sections are screwed together, so as to removeanyroughness about the 4joint due to inaccuracy in fitting.

In the cavity as a wad of cotton w may be placed to receive and absorbthe nicotins, and this cotton may carry chemical substances designed toneutralize the nicotine.

C is the mouthpiece of the stem, and D is a 'core attached to saidmouthpiece and designed tooccupy a bore in the stem B. Figs. l, 1, 2 and2 illustrate the preferred manner of con' structing this core with aview to the admis-A sion of air in regulated quantities to` thesmoke-passage in'the core and mouthpiece. In these views the mainportion or body of the core D is cylindrical, and is adapted to fitsnugly into the main bore in the stem lB. At its end is a shortcylindrical portion d, which isl eccentric to the body and is adapted toe11- ter and t a counterbore in the stem, which counterbore connects themain bore therein with the cavity or chamber a in the lower sectionofthe bowl. The core Dvhas a longitudinal slit d in it, which adapts thecore to iit expansively and tightly in the mainbore of the stem wheninserted, somewhat in the man-` ner of a split key. In the lower side ofthe core is formed a channel d', and in its upper sidey is formedachannel d2.- These channels communicate at a point near the mouthpiecewith the smoke-passage c; The upper channel d2 extends to the end of thereduced por-- tion d of the core, and forms a smoke-passage to lead thesmoke fromthe bowl to thepassage c, and the lower channel d' forms anairpassage, which will be hereinafter described. It will be seen thatthe wall of the bore in the stem B forms one wall of the respectivesmoke and air passages, the channels d' and d2 being open grooves in thecore. These grooves may be much more cheaply and conveniently home theentry of air to the passage h is cut oi. Any known device of thischaracter may be employed, that shown being preferred.

Fig. 3 shows a construction slightly dierent from that alreadydescribed. The part d is omitted from the core D, and the core is notslitted longitudinally. Otherwise there is no material diEerence.

The construction of the core with the part d insures its properinsertion in the stem, and the slitl insures a snig it in the bore ofthe stem. l

I t will be seen by inspection that while the large bore in the stem ofthe pipe is open bot-h to the bowl and the air-inlet -the core, wheninserted, interposes a barrier between said air inlet or passage and thepassage leading from the bowl to the groove d2, thus compelling thesmoke and air to traverse the respective grooves in the core to thepoint where they unite with the smoke-passage c.

Of course I do not limit my invention to wooden pipes; but in manyrespects it is well 5o adapted to this class of pipes.

Having thus described my invention, I claimv 1. In a pipe, thecombination with the stem having a relatively large borewhichcommunicates at itsinner end with the bowl of the passage, and a core D,secured to saidmouthpiece and adapted to iit snugly in the enlarged borein the stem, said core having two longitudinal passages, d and cl2, bothcommunieating at their outer ends with the smokepassage in themouthpiece, the former communicating at .its front endwith the air-inlet to the stem, and the latter communicating at its front end with thebowl of the pipe, substantially as set forth.

2L In a pipe, the combination with the-stem, having a relatively largebore which communicates at its inner end with the bowl of the pipe andbya lateral passage in the stem with the air, and a mouthpiece having init a smoke-passage, of a core D, secured to said mouthpiece, said corehaving a short cylindrical portion d, which projects beyond the mainportion into the bowl, and said core having also two separate passages,d and cl2, for the air and smoke, respectively, which passages connectat a point near the mouthpiece with the smoke-passage therein.

3. The combination with the stem and bowl of a pipe, said stem having init a relatively large longitudinal bore, communicating at its inner endwith the bowl and by a lateral passage, with the air, of the mouthpiece,and the core, D, secured to said mouthpiece, said core having alongitudinal slit dx, two oppositely arranged longitudinal grooves,d'andd, and a smoke-passage c, with whichv said channels communicate, asset forth.Y

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
